n-Propylamine

N-Propylamine (CAS 107-10-8, EC 203-462-3) is a short-chain primary aliphatic amine with the molecular formula C3H9N, also referred to as propylamine or propanamine. It carries no E-code designation. It is registered under REACH and classified as a flammable, corrosive substance requiring compliant handling across EU markets.

In pharmaceutical synthesis, n-propylamine acts as a building block and pH buffer, donating its primary amine group to form stable salt complexes with active ingredients. In polymer and adhesive manufacturing, it functions as a crosslinker by reacting with epoxy or isocyanate groups to build covalent network structures that improve mechanical durability.

N-Propylamine is available in technical and high-purity grades suitable for pharmaceutical and food-contact applications. Relevant compliance frameworks include REACH registration and FCC standards where food-grade use applies. It is typically supplied in drums or IBC containers, with documentation including SDS and certificate of analysis provided on request.
